Abstract: Aspects of the present disclosure are presented for efficiently allocating resources to projects in a schedule under time, resource and budget constraints. In some embodiments, a method is presented. The method may include accessing variables for determining an efficient allocation of resources in the schedule, including a set of project dependency values indicating which projects in the plurality of projects must be completed as requisite for completing other projects in the plurality of projects. The method may also include determining a dependency path indicating an ordering of projects to be completed, based on the set of project dependency values, wherein a project in the dependency path cannot be started until all preceding projects in the dependency path are completed; and determining an efficient selection of projects to be completed within the time horizon that maximizes an optimization goal, based on the dependency path and constrained by budget expenditures.
